...at least they are hiting each other, hah. Some of it looks choreographed though. Is it just fully fake?

It mostly looked like legit Sanda/Sanshou fighting to me (striking and takedowns, but no groundfighting) .

The only weird thing about it was the way that last guy falls down at the end of the clip- that looked kind of staged, or something.They weren't wearing any safety gear, either, unlike most Sanda/Sanshou clips I've seen.
